The Elkins Hypnotizability Scale: Assessment of Reliability and Validity

Measuring hypnotizability is an integral part of hypnosis research and also relevant for predicting the effectiveness of hypnosis-based therapies. The Elkins Hypnotizability Scale (EHS) was designed to meet the needs of modern hypnosis research and clinical practice. Reliability, validity, and normative data were explored by subjecting 230 participants to the EHS and Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C). The EHS demonstrated adequate internal consistency (α = .78), its items showed good discriminating ability, and scores of the two scales were highly correlated (rho = .86). Results indicate that the EHS is a reliable and valid tool to assess hypnotizability. Further research is needed to establish its role as a surrogate for the SHSS:C.
